  • Implantable cardiac stimulator with physiologic sensor based on mechanical-electric phase relation
    Patent number: 5999854
    Abstract: A cardiac pacemaker includes circuitry which receives a raw impedance signal from the sensor leads of the pacemaker, derives data from the impedance signal that is descriptive of the impedance signal over an entire (or a large part of the) cardiac cycle, develops first order parameters which define that cycle, and provides these parameters to a microprocessor for control of the pacing signal. These parameters may also be used to determine other information about the functioning of the pacemaker. The present invention may also be applied to the determination of tachycardia of an intrinsically paced heart, as well as other applications.
